An ace is plenty impressive, but calling your shot makes it all the more intriguing. That's what Nicklaus did in an interview with ESPN's Scott Van Pelt before teeing off in the contest Wednesday.

Nicklaus said he had never recorded an ace at Augusta National. Part of the piece of history created today now belongs to his grandson, Stevie. Grandpa Jack gave Stevie the Nicklaus Black ball used for the hole-in-one along with the golf glove.
